/wf5-implement

Implement one step of the Plan document.

Usage

/wf5-implement [step_number]

Arguments

• step_number: Step to implement (optional). Auto-selects next incomplete step if omitted.

Constraints

• No Off-Plan Changes: Only implement what is documented in the Plan.
• One Execution = One Step: Only one step per execution.

Processing

1. Check Prerequisites

Get active work. Require 03_PLAN.md exists.

2. Determine Target Step

If no argument: current_step + 1 from state.json. Check dependent steps are completed.

3. Extract Step Info from Plan

Title, Purpose, Target Files, Tasks, Completion Criteria, Dependencies.

4. Implementation

1. Load and analyze target files
2. Make code changes following Plan tasks — no off-plan changes
3. Run related tests; fix failures if directly related to this step's changes

5. Record Implementation Log

Append to 05_IMPLEMENT_LOG.md using template ~/.claude/templates/05_IMPLEMENT_LOG.md.

6. Update state.json

Set step status to "completed" with timestamp. Update current_step. Set current: "wf5-implement". If all steps done, set next: "wf6-verify".

7. Verify Completion Criteria

Check each criterion is satisfied.

8. Commit

Auto-detect commit type from step content:

• bug/fix/repair → fix
• refactor → refactor
• test → test
• doc/documentation → docs
• otherwise → feat

Override with commit.type_detection/commit.default_type from config.json.

Message: <type>(<scope>): <description> with step info and work-id in body.

9. Completion Message

Show changed files with diff stats, completion criteria results, progress (n/total), next step suggestion.

Off-Plan Changes

• Minor (typos, imports): Record in Notes section, continue
• Significant (design changes): Interrupt, suggest /wf3-plan update
